Public Attributes | |
int | bit_rate |
The bit rate of the modem. Valid values are 4800, 7200 and 9600. | |
get_bit_func_t | get_bit |
The callback function used to get the next bit to be transmitted. | |
void * | get_bit_user_data |
A user specified opaque pointer passed to the get_bit function. | |
modem_status_func_t | status_handler |
The callback function used to report modem status changes. | |
void * | status_user_data |
A user specified opaque pointer passed to the status function. | |
float | gain |
The gain factor needed to achieve the specified output power. | |
const complexf_t * | constellation |
A pointer to the constellation currently in use. | |
complexf_t | rrc_filter [2 *9] |
The root raised cosine (RRC) pulse shaping filter buffer. | |
int | rrc_filter_step |
Current offset into the RRC pulse shaping filter buffer. | |
int | diff |
The current state of the differential encoder. | |
int | convolution |
The current state of the convolutional encoder. | |
int | constellation_state |
The code number for the current position in the constellation. | |
uint32_t | scramble_reg |
The register for the data scrambler. | |
int | in_training |
Scrambler tap. More... | |
int | short_train |
TRUE if the short training sequence is to be used. | |
int | training_step |
A counter used to track progress through sending the training sequence. | |
uint32_t | carrier_phase |
The current phase of the carrier (i.e. the DDS parameter). | |
int32_t | carrier_phase_rate |
The update rate for the phase of the carrier (i.e. the DDS increment). | |
int | baud_phase |
The current fractional phase of the baud timing. | |
int | bits_per_symbol |
The current number of data bits per symbol. This does not include the redundant bit. | |
get_bit_func_t | current_get_bit |
The get_bit function in use at any instant. | |
logging_state_t | logging |
Error and flow logging control. | |
V.17 modem transmit side descriptor. This defines the working state for a single instance of a V.17 modem transmitter.
int v17_tx_state_s::in_training |
Scrambler tap.
TRUE if transmitting the training sequence. FALSE if transmitting user data.
